A A Specification forming part .of Letters Patent No. 200,875, dated March 5, 1878; application filed I v; A A .J a December 24, 1877.

. Be it known. thatl, Firmwares. tastes of Boston, in the countyof.Sufi'olk ,--:State.of

Massachusetts, have? invented? .;a certain anew and useful Improvement in SolderingwAppah ratus, of which-the following isia description A sufficiently full, clear, and exact'toenable any person skilled in (the --artror science to which 3 my invention appertains to make and use the. same, reference being had to the-accompany of the isarne;-fFig. r-4, sectional views of the arms or holders; Fig. 5, avplan viewofthe chimney-holder, and also a reduced transverse J section of the chimney. 2 A

ing apparatus in which the iron is heated by A means of the flame of a lamp or a gas-jet; and consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, by which a simpler, cheaper, and more effective device of this character is produced than is now in ordinary use.

The nature and operation of my invention will be readily obvious to all conversant with such matters from the following description.

In: the drawings, Agrepresents the chimney or body of the apparatus, which is preferably composed of sheet metal, and is provided with a glazed opening, B, and hinged cover 1. The chimney is secured to the holder 0 by the screws (1 d, and'is a parallelogram in crosssection, as seen at A, Fig. 5, one of its edges,

10, being rounded, and the other,-12, at right angles with its sides. 3 V

Through the edge l2'there is an oblong aperture, y, designed to receive andadm'it of the vertical adjustment of the circular lip or flange z, surrounding an opening in and form in g a part of the plate :0 w. This plate is arranged on the interior face of the edge 12 of the chimney A, and is secured thereto by the Figure 1 is aside elevation "of thesoldering- 1 iron ,Fig. 2, arperspective view'of-theappa: v ratus Fig. 3, a :long-itudinal vertical-section A screws 0 0, which pass through elongated slots .9 y, as shown.

Attached to the plate ac, by the screw 91*, there is a plate, m, provided with-two inwardly-projecting parallel arms or holders, 1, one only being shown. These arms are about threefourths of an inch apart, being straight on their lower edges, and so constructed and arranged that their inner ends are slightly lower thanthe outer ends, or that part nearest the opening surrounded by the flange z.

A corresponding pair of arms, K, project from the plate 2', which is attached to the plate why the screw n, the inner ends of the last-- named arms being also lower than the outer ends of the same, and their upper edges straight; 1 j The plates z and m are both rendered-adjustable on the plate as by their respective screws n n and the slots in which they work, the plate '5 being arranged below, and the plate m above, the opening in the plate as, which is surrounded by the flange 2.

Attached to the inner face of the curved edge 10 of the chimney A there is a stud or stop, Q, having two downwardly-sloping sides, as shown, and immediately opposite this stop or stud the top of the edge 12 of the chimney is provided with a V-shaped notch, as seen at r. The broad or flattened sides of the chimney A are not so long or do not rise so high as the edges, so that when the cover 1) is closed ample spaces are left under the same for the passage of the smoke and heated air to keep up a proper draft.

The soldering-iron S is of the ordinary construction, having the shank t and handle to but on the shank t there is an adjustable collet, u, provided with the flange or face-plate o.

In the use of my improvement, the. chimney A is jointed to a lamp (not shown) by the hinge f, the plate 0 being provided with a cone, 9, for directing and controlling the flame. The arms or holders K I having been properly adjusted on the plate as by means of the screws n M, with reference to the aperture surrounded by the flange z and the size of the soldering-iron S, the plate a: is then adjusted by means of the screws 0 0, with reference to the cone g, to bring the arms K Z to a proper distance above the flame of the lamp. The iron Sis then inserted through the aperture in the plate as, as seen in Fig. 2, until the flange of the collet u comes into contact with the outer edge of the flange z, where it will be held by the arms K I, and readily heated; or it may be heated by inserting the point under the stud Q, and dropping the shank t into the notch r, as shown by the dotted lines in Fig. 2.

The object of constructing the chimney in the form shown, viz., with flattened sides and one straight and one rounded edge, is to make it conform, as nearly as practicable, to the.

shape of the body of the soldering-iron, and thus concentrate the heat more directly and uniformly upon the same than could otherwise be done.

The object of depressing the inner ends of the arms or holders K I is to compensate for the gravitation of the handle w, and thus bring the squared faces of the flanges v 2 into perfect contact, and completely close the open= ing inthe plate as, through which the iron is inserted into the chimney, the flange '0 serving as a door for this purpose, and also as a rest to prevent the iron from coming into contact with the bench of the workman when not in use.

In place of. the lamp-flame for heating the iron, the chimney may be used with a gas-jet, lt'preferred, the burner being arranged as shown bythe dotted lines h.

"The arms K are perforated, as seen in Figs. 2 and 3, to enable the flame and heated air to passlnore readily to the iron; but instead of this they may have their edges corrugated, as shown in Fig. 4, if desired. It'will also be obvious that a series of openings can be made in the chimney, and provided with arms or holders, in such a manner that several irons may be heated at the same time, if necessary.

Having thus explained my invention, what I claim is- 1. In a soldering apparatus, the chimneyA, provided with the holdersz lupK and an opening through which the iron is inserted, substantially as and for the purpose specified.

. 2. In a soldering apparatus, :the holders 1 K, having their inner ends depressed, substantially as and for the purpose set forth.

3. In a soldering apparatus, the chimney A, and flange z, in combination with the flange o, substantially as and forhthe purpose set forth and specified. Y 1 I '4. In a soldering apparatus, the .chimneyA provided with the stud Q and notch r, substantially as and for the purpose'specified.

5. In a soldering apparatus, the adjustable plate as, provided with the .flange z, in combination with the chimney A,rsubs.tantially as and'for the purpose set forth. and specified.

6. The cover 11, hinged t0.;the top of the chimney A, said chimney beingprovided with a lateral opening, through :Whiflh thesoldering-iron is inserted, and withtheholders ZK, substantially as and for the purpose specified.
